natum, membranaceo-chartaceum, ca. 12 mm. longum, uniloculare vel partim 
semibiloculare, pube breve griseo, calycem subduplo superans. 
Herschell Isl. In full flower on July 13th, 1906 (and with year- 
old pods). 
I have been much in doubt as to the identification of this pretty 
Oxytropis. It belongs to the relationship of O. Lamberti PursH and 
O. monticola Gray (cfr. A. Gray, in Proc. Americ. Acad. Arts & Sciences, 
vol. 20, 1885, p. 6); but is rather different from both. The smaller flowers 
and the dark pubescence of the calyx distinguish it from the true O. Lam- 
berti of Colorado and Montana, and the same characters as well as the 
subcapitate inflorescence and the longer pod from the O. monticola of 
Wyoming, Montana and Nebraska, as far as I can judge from Gray’s 
description and from examination of specimens from South Sybille (Al- 
bany Co.) and from Pipestone Creek, N. W. T. 
J. Macoun points out (Catalogue Canad. Pl. III, 1886, p. 509—3510) 
that his former O. Lamberti also includes O. monticola, but as he at the 
same time (p. 509) quotes specimens from Kicking Horse Lake (Rocky 
Mts.) under O. Lamberti, I think he means that they belong to the true 
O. Lamberti, not to O. monticola (which in his opinion »is the true prairie 
form«). These specimens of which we have a set in the Copenhagen 
herbarium, are not like O. Lamberti from Colorado and Montana, but 
come very near my new species, from which they only differ in having 
yellow flowers. I think they are a southern representative of our species. 
To our species also the record of O. Lamberti from Klondike, 
Alaska (James Macoux, Ottawa Naturalist, Dec. 1899, p. 211) may be 
referred. And probably we must place here O. Lamberti, 8, foliolis bre-
